comment
  • FUNCTION Involved in synthesis of starch. Catalyzes the synthesis of ADP-glucose, a molecule that serves as an activated glycosyl donor for alpha-1,4-glucan synthesis. Essential for starch synthesis in leaf chloroplasts.CATALYTIC ACTIVITY alpha-D-glucose 1-phosphate + ATP + H(+) = ADP-alpha-D-glucose + diphosphateACTIVITY REGULATION Activated by 3'phosphoglycerate, inhibited by orthophosphate. Allosteric regulation.PATHWAY Glycan biosynthesis; starch biosynthesis.SUBUNIT Heterotetramer composed of two small and two large subunits.SUBCELLULAR LOCATION Expressed in leaves and stems.DEVELOPMENTAL STAGE Expressed in developing seeds from 1 to 20 days after flowering (DAF).INDUCTION Induced by sucrose and glucose.SIMILARITY Belongs to the bacterial/plant glucose-1-phosphate adenylyltransferase family.
